To all 'whom it may concern:

Be --it known that I, JOSEPH IMCLANE, a -citizen of the United. States,residing) at 'Washingtom in the: District of Clum ia,-

have inventedcertain new'and useful Imvprovements in `a'. WeftlessTire-Forming Cord Band, of which the following isa specification.

This invention relate-s to a Vform of .textile- `for the production-of`a weftless Acloth for use articularly designed for the enstructon'o the(carcass ofppneumatc tire casings andof the general type known as cordtires. In this pe of tire the distinguishing characteris-- tlc-has beento retain ,aI weft weave only for the purpose of temporarilyv holdingthe cords or warps parallel. and in sheet formation', and are used-inVgreater or less num-l ber, the resence of' which inthe manufactured ruberized cloth causes `-lack of uni- Y, formity an insuiiicientl tensionand-'undulations of thev cords, imperfect'coating of the cords' withrubberA with consequent weak spots and separation ofthe rubber from thecords, besides producing a source of frictional heat and otherobjectionable features in the tire built of this form of weft c ordcloth. The object therefore of the present invention is to eliminate theweft threads from f the rubberized cloth vand avoid all the consequentdisadvantages due to' thepresence of weft threads in tires, aswell asthe saving of the cost `of the weft threads and the' weaving costthereof, and the making of a form of weftless cord bandsthat can be.

hand-tying. operation required in beaming a 'large number of cords,while at the same time la form o f cord band is produced suitable for:ictioning directly through thev 5 Yrolls of a calendar by reason of themeans by which the cords yare heldin `their proper parallel and. equallystressed condition in theon the'beam and theA u ncords terminating at'oneend in a ilexible winding portion preferablyof fabric weave ,form endfabric tedious ,-to provide a Iiexibleiheader, for beginning the on thebeam, and at its other end w1th a similar` flexible winding portionfor'startlng the v,winds on the usual wind-up roll, 4so that all thecords will be maintained accuratelyv spaced' and no undue yskill or timerequiredl in the operation of beamingorA installing a beam andconnecting the band with its wind-u roll in readiness vfor drawing thesame. through the calender.

lIn thefbeaming of these'eord bands with their terminal fabric ends, thecords will pass from their spools through a vlool'n that' will boperated to weave. a portion of'L-the' bands only where the fabric endsare desired and for the purposeof beaming short ban lengths of 1501yardsor other commerclal. l"

' length, theY terminal'fabridportions may be Imade by intermediateweaving of the bands il' and the cutting' through the same to divide thefabricA portion and form'fabric end por-y tions." i

Y Figure `1 illustrates the weitless 'corda' band having the terminalfabric ends, `and Figure-Q'illustrates a len h of band to be cut intoseveral lenV s by cutting through the intermediate abric weaving to Aportions for ,the shorter lengths;

Referring to the drawings,v 10 indicates 'the cords ofthe weftless'band' and Y11 the fabric terminal portion of the band'. Except forthese termlnal portions the c'ords are free of any cross support, butunder the f winding and spacin initiated. by the fabric fend portionsand t e equal tension resulting from the umform stress of-the wound'woven portion asl an attaching and draW- ing Ymeansthese free cords aremaintained in their sheetformatiomvso that in calendering or inimpregnating they will not be caused to overlapV each other. or form -1nthe rubberized cloth what are known as vhard' and soft spots but producea uniformproduct. lV-henV it is desirable to form'the short' Ico' llio

lengths for convenient shipping to and use by the trade the intermediatefabric portions 11 are made and cut through on the line a/-a to form endfabric portions for the shorter lengths.

It Will be seen that by this form of cord band a product'is finishedthat, both from the textile' producing end and the use thereof informing Weftless rubber cloth, presents many economies and advantages,and with the further results that a superior tire may be constructedtherefrom and at less cost and labor.

What I claim, is:

1. A textile article of manufacture for ythe continuous production ofWeftless rubberized cloth therefrom during the passage of the samethrough suitable rubber-applying means, said article comprising amultiplicity of cords or Warps arranged in parallel relation to form aWeftless band of relatively great length and terminating in Wovensections at each end adapted to provide means for maintaining the cordsor Warps in flat parallel 4relation and furnish a Wind-'up portion uponwhich the cords of the unwoven length of the band are wound in parallelrelation and maintained in such relation in the winding.

2. A textile article of manufacturefor the continuous production `ofWeftless rubberized cloth therefrom during the passage of the samethrough suitable rubber-applying means, said article comprising amultiplicity of cords or Warps arranged in parallel relation to form aWeftless Wound band thereof of relatively great length terminating in atransverse Woven portion at one end and connecting the cords or Warps inflat parallel relation and adapted to provide a Wind-up portion for. theinitial Winding of the band, and a terminal transverse portionconnecting the cords or Warps together in band-formation at the otherend, whereby the cords or bands in being unWound and rewound Will travelduring the application ofthe rubber in uniform band formation.

3. The method of forming a band of parallel cords of relatively greatlength for the' continuous production of Weftless rubber cloth therefromby suitable rubberapplying means during the passage of the band of cordstherethrough, Which method consists in first Weaving the cords to form afabric section for connecting them in their parallel band formation,Winding thev cords in such formation upon the fabric section, Weaving atintermediate points of the band of cords other woven sections, to formtherebetween a band section of the cords of relatively great length, andcutting through the intermediate Woven sections to form the commerciallengths of the band with a fabric Wind-up section at each end thereof,as and for the purpose set forth.

In testimony whereof I afx my signa- JosEPH A. MCLANE.
